In the following, you can find some major milestones of the BARC past activities. To be updated in the next future!

February 2021 - MYOC BARC webApp online

Posted on by BARC organizing committee


12 years later BARC launching, a new web app is available to collect, postprocess and compare the large amount of scientific results obtained by the international community on the BARC flow. BARC-MYOC (Make Your Own Comparison) is available here.

Enjoy using it!

June 2020 - BARC new website online

Posted on by BARC organizing committee

On the occasion of the new ANIV website, also BARC renews its one.
The new web site is full Open Access, with no longer a credential-based member area.
Docs and Data section are enriched, and a web-based BARC-MYOC App (Make Your Own Comparison) included to quickly postprocess results from previous contributes, and compare them with new results.
A special thanks to the Executive Board of the International Association for Wind Engineering, headed by Y. Tamura, that supported BARC dissemination activities in 2014.

May 2014 - BARC in ERCOFTAC Wiki

Posted on by BARC organizing committee

BARC enters as Silver content among the Underlying Flow Regimes (UFR_2-15) in the ERCOFTAC Knowledge Base Wiki

A great recognition from the widest and most renewed European research community in turbulence and combustion.

A great contribution by ERCOFTAC to boost BARC dissemination.

A special thanks to Wolfgang Rodi, ETCOFTAC delegate in the BARC Scientific committee, who made this possible.


January 2014 - BARC overview published on JWEIA

Posted on by BARC organizing committee

Bruno, L., Salvetti, M. V., & Ricciardelli, F. (2014). Benchmark on the aerodynamics of a rectangular 5:1 cylinder: An overview after the first four years of activity. JWEIA126, 87–106.


An outline of the state of the art on the aerodynamics of 5:1 rectangular cylinders prior to BARC, and a summary of the results obtained by the contributors during the first four years of activity. About 70 realizations of the BARC flow in both wind tunnel experiments and numerical simulations.

A special thanks to all BARC participants, and JWEIA editor and anonymous reviewers, who made this possible.

Updated statistics at:

July 2011 - BARC at ICWE13 – Amsterdam

Posted on by BARC organizing committee

BARC Thematic Session at 13th International Conference on Wind Engineering, in the wake of the ones at EACWE5, and CWE2010. The session hosts 9 papers.




BARC Young Authors Award remitted to:

  • André F. P. Ribeiro for his study “Unsteady RANS modelling of flow past a rectangular 5:1 cylinder: investigation of edge sharpness effects”;
  • Okke Bronkhorst for his study “Unsteady pressure measurements on a 5:1 rectangular cylinder”.

March 2009 - BARC website online

Posted on by BARC organizing committee


A special thanks to V. Gusella, at the time president of ANIV, and M. Gioffrè, designer and administrator of the site, who made this possible.

July 2008 - BARC kickoff at BBAA VI – Milan

Posted on by BARC organizing committee

BARC is presented at 6th International Colloquium on

Bluff Body Aerodynamics & Applications

The BARC presentation is complemented by announcements on JWEIA, JFS, C&F, Wind&Structures, J. Flow, Turbulence and Combustion
A special thanks to Alberto Zasso, BBAAVI Chairman, and to Guido Buresti, chairman of the Rectangular Cylinder session, who made this possible.
